Michael,

yes, understood and appreciated.

but it is already implemented. Just some "shadow" functions
parallel to the existing point click tool. Since line length
measurement is already there, drawing a line should be easy
(needed for rectify-by-line tool). Also box is already
there from zoom, so drawing a box should be easy (needed for
auto-search-of-GCPs-in-corresponding boxes).

It doesn't.

Of course. I just wanted to remind people that the tool is there.
Once there was quite some interest.
